Abstract

[Object] To realize control that, in control of facility equipment, reduces electricity charges, taking into consideration fluctuation in power amount charge unit prices, and also a relation between a prediction value of power usage and a greatest value in a relevant period. [Solution] A control device that generates control information for controlling facility equipment of a consumer includes an information acquisition unit that acquires information of a power amount charge unit price that fluctuates and information of power usage of the consumer, and a control information generating unit that, on the basis of the power amount charge unit price in an object interval that is an interval in which control of the facility equipment is performed and information of power usage of the consumer in an interval after the object interval, generates control information for the facility equipment of the consumer in the object interval.

Claims (34)

1 . A generating device that generates control information for controlling facility equipment of a consumer, the generating device comprising:

a processor and a storage storing a program that causes the processor to,

acquire information of a power amount charge unit price that fluctuates;

acquire information of predicted power usage of the consumer;

on a basis of the power amount charge unit price in an object interval that is an interval in which control of the facility equipment is performed and information of entire predicted power usage of sets of facility equipment of the consumer in an interval after the object interval, generate control information for the facility equipment of the consumer in the object interval, the object interval being an interval during operation of the sets of facility equipment; and

transmit the generated control information to the facility equipment,

wherein, the program causes the processor to perform a suppression control when the power amount charge unit price is higher in an interval before the object interval, and the program terminates the suppression control when the suppression control causes the power usage during the object interval to exceed the contract demand,

wherein the program causes the processor to determine whether the power usage of the consumer after load control in an interval after the object interval is expected to exceed a contract demand, which is a largest value of a largest demand power within a past year from a current month, and generate the control information to control the facility equipment so as to suppress power usage in the object interval only in a case in which the power amount charge unit price in the object interval satisfies a predetermined condition and the determined power usage of the consumer after load control in the interval after the object interval is not expected to exceed the contract demand, and

wherein, the facility equipment, based on the control information, reduces power usage during the object interval below the contract demand, and increases the power usage during the interval after the object interval while maintaining the power usage below the contract demand to maintain an average power usage below the contract demand.

2 . The generating device according to claim 1 , wherein, in a case in which the power usage of the consumer in an interval after the object interval is expected to exceed a reference power and in which the power amount charge unit price in an interval immediately prior to the object interval is no greater than the contract demand unit price, the program causes the processor to generate control information to implement preliminary operation of the facility equipment in the interval immediately prior to the object interval.

3 . The generating device according to claim 2 , wherein, with regard to air conditioning equipment included in the facility equipment, the program causes the processor to generate control information to implement preliminary cooling operation or preliminary heating operation in an interval immediately prior to the object interval, in accordance with operation to be implemented in an interval next after the object interval.

4 . The generating device according to claim 1 , wherein the program further causes the processor to:

acquire information of a contract charge unit price, which is used in conjunction with information of greatest demand power of the consumer to set a base foe, and

generate the control information on a basis of an electricity charge of the consumer over a certain period, which is determined from the power amount charge unit price, information of the predicted power usage of the consumer, and the contract charge unit price.

5 . A system, comprising:

a processor and a storage storing a program that causes the processor to,

generate control information for controlling facility equipment of a consumer;

the system including facility equipment that accepts the control information generated in the generate step and performs action,

in the generate step, the program further causes the processor to,

acquire information of a power amount charge unit price that fluctuates,

acquire information of predicted power usage of the consumer,

on a basis of the power amount charge unit price in an object interval that is an interval in which control of the facility equipment is performed and information of entire predicted power usage of sets of facility equipment of the consumer in an interval after the object interval, generate control information for the facility equipment of the consumer in the object interval, the object interval being an interval during operation of the sets of facility equipment; and

transmit the generated control information to the facility equipment,

wherein, the program causes the processor to perform a suppression when the power amount charge unit price is higher in an interval before the object interval, and the program terminates the suppression control when the suppression control causes the power usage during the object interval to exceed the contract demand,

wherein the program causes the processor to determine whether the power usage of the consumer after load control in an interval after the object interval is expected to exceed a contract demand, which is a largest value of a largest demand power within a past year from a current month, and generate the control information to control the facility equipment so as to suppress power usage in the object interval only in a case in which the power amount charge unit price in the object interval satisfies a predetermined condition and the determined power usage of the consumer after load control in the interval after the object interval is not expected to exceed the contract demand, and

wherein, the facility equipment, based on the control information, reduces power usage during the object interval below the contract demand, and increases the power usage during the interval after the object interval while maintaining the power usage below the contract demand to maintain an average power usage below the contract demand.

6 . A non-transitory computer readable medium storing a program that causes a computer to:

acquire information of a power amount charge unit price that fluctuates;

acquire information of predicted power usage of a consumer; and

on a basis of the power amount charge unit price in an object interval that is an interval in which control of the facility equipment of the consumer is performed and information of entire predicted power usage of sets of facility equipment of the consumer in an interval after the object interval, generate control information for the facility equipment of the consumer in the object interval the object interval being an interval during operation of the sets of facility equipment, and

transmit the generated control information to the facility equipment,

wherein, the program causes the processor to perform a suppression control when the power amount charge unit price is higher in an interval before the object interval, and the program terminates the suppression control when the suppression control causes the power usage during the object interval to exceed the contract demand,
